django urlconf直接从根到包含的应用程序逻辑

[英]django urlconf direct from root to included app logic

 原文  2017-07-10 20:25:43  5   1    python/ django/ routes/ django-urls/ urlconf

问题描述

我已经尝试解决这个问题了一段时间，但一直没有找到有效的解决方案。 也许有人可以帮助指出更好的方法！

我正在使用根urlconf将两个请求重定向到包含的应用程序： 

url("^about/news/", include("kdi.urls")),
url("^about/recognition/", include("kdi.urls")),

这是kdi应用的urlconf： 

url(r"^$", "kdi.views.news", name="news"),

# this is the pattern that needs to change:
url(r"^$", "kdi.views.recog", name="recog"),

使用从根^about/news/和^about/recognition到应用程序urlconf中的^$的更精细的重定向似乎更聪明。 这仅适用于一种模式，但我想对其进行扩展以使其适用于两种模式。

将^about/从根目录引导到可以在kdi应用中检查^/news$或^/recognition$的应用中， kdi会更聪明？ 如果未进行匹配，那还能使用根的全包^吗？ 是否可以从urlconf中检查request.path ，然后使用if语句将其定向到正确的视图？ 还是可以在根目录中使用name字段，然后通过应用程序的网址格式中的该名称进行访问？

只是有点麻烦，以此来确定逻辑！

编辑：

从根urlconf中删除了namespace字段以限制混乱

您在这里做的事情很奇怪，我不知道为什么。

您只应添加一次应用网址。 但是该包含文件中的每个URL都必须不同 -否则Django无法知道如何路由请求。

因此，主要的urls.py应该只是： 

url("^about/", include("kdi.urls")),

和应用程序应该是： 

url(r"^news/$", "kdi.views.news", name="news"),
url(r"^recognition/$", "kdi.views.recog", name="recog")
